Beyond Lenses: New 3D Camera Sees the Invisible in High Detail

Traditional infrared cameras are often bulky, expensive, and struggle to focus on objects at varying distances. To solve this, scientists developed a lens-free camera using a laser-generated "optical pinhole." This system converts invisible heat signals into sharp 3D images without the distortion caused by glass lenses. The benefit is more affordable, portable night vision for cars, improved industrial safety, and better tools for monitoring environmental pollution from afar.
